### Question-1

Problem Statement – Write a program to calculate the fuel consumption of your truck.The program should ask the user to enter the quantity of diesel to fill up the tank and the distance covered till the tank goes dry.Calculate the fuel consumption and display it in the format (liters per 100 kilometers).

Convert the same result to the U.S. style of miles per gallon and display the result. If the quantity or distance is zero or negative display ” is an Invalid Input”.

[Note: The US approach of fuel consumption calculation (distance / fuel) is the inverse of the European approach (fuel / distance ). Also note that 1 kilometer is 0.6214 miles, and 1 liter is 0.2642 gallons.]

The result should be with two decimal place.To get two decimal place refer the below-mentioned print statement :

float cost=670.23;

System.out.printf(“You need a sum of Rs.%.2f to cover the trip”,cost);

Sample Input 1:

• Enter the no of liters to fill the tank

20

• Enter the distance covered

150

Sample Output 1:

• Liters/100KM

13.33

• Miles/gallons

17.64

Explanation:

• For 150 KM fuel consumption is 20 liters,
• Then for 100 KM fuel consumption would be (20/150)*100=13.33,
• Distance is given in KM, we have to convert it to miles (150*0.6214)=93.21,
• Fuel consumption is given in liters, we have to convert it to gallons (20*0.2642)=5.284,
• Then find (miles/gallons)=(93.21/5.284)=17.64

Sample Input 2:

• Enter the no of liters to fill the tank

-5

Sample Output 2:

• -5 is an Invalid Input

Sample Input 3:

• Enter the no of liters to fill the tank

25

• Enter the distance covered

-21

Sample Output 3:

• -21 is an Invalid Input

### Question-5

Problem Statement  – In a theater, there is a discount scheme announced where one gets a 10% discount on the total cost of tickets when there is a bulk booking of more than 20 tickets, and a discount of 2% on the total cost of tickets if a special coupon card is submitted. Develop a program to find the total cost as per the scheme. The cost of the k class ticket is Rs.75 and q class is Rs.150. Refreshments can also be opted by paying an additional of Rs. 50 per member.

Hint: k and q and You have to book minimum of 5 tickets and maximum of 40 at a time. If fails display “Minimum of 5 and Maximum of 40 Tickets”.  If circle is given a value other than ‘k’ or ‘q’ the output should be “Invalid Input”.

The ticket cost should be printed exactly to two decimal places.

XYZ Technologies is in the process of increment the salary of the employees.  This increment is done based on their salary and their performance appraisal rating.

1. If the appraisal rating is between 1 and 3, the increment is 10% of the salary.
2. If the appraisal rating is between 3.1 and 4, the increment is  25% of the salary.
3. If the appraisal rating is between 4.1 and 5, the increment is  30% of the salary.

Help them to do this,  by writing a program that displays the incremented salary. Write a class “IncrementCalculation.java” and write the main method in it.

Note   :   If either the salary is 0 or negative  (or) if the appraisal rating is not in the range 1 to 5 (inclusive), then the output should be “Invalid Input”.

Sample Input 1 :

• Enter the salary

8000

• Enter the Performance appraisal rating

#### Question-12

Problem Statement – Mayuri buys “N” no of products from a shop. The shop offers a different percentage of discount on each item. She wants to know the item that has the minimum discount offer, so that she can avoid buying that and save money.
[Input Format: The first input refers to the no of items; the second input is the item name, price and discount percentage separated by comma(,)]
Assume the minimum discount offer is in the form of Integer.

Note: There can be more than one product with a minimum discount.

Sample Input 1:

4

mobile,10000,20

shoe,5000,10
